The Design and Implementation of a Performance Examination System for Police Office Based on Web

公安部于2004年提出了全国公安信息化的建设规划，旨在接下来的几年内通过信息化建设规范工作、提高效率，从而进一步提高全国公安的战斗力，其中公安绩效管理系统是一个重要的内容。根据规划精神，为进一步优化绩效考核体系，提升绩效考核的效能，解决对民警量化考核的各种问题，各市公安机关都开始尝试调整传统的绩效考核体系，逐步将以块为主的考核模式建设成为全方位的立体型绩效考核体系，使民警的绩效考核实现精细化管理。 课题研究通过当前各地公安机关的管理模式和管理方法，收集绩效考核管理标准规范，结合某公安局的实际工作特点和详细需求，分析并设计了绩效考核系统原型。设计的绩效考核系统贯穿了整个流程，提供考核指标管理、...In 2004, Ministry of Public Security brought forward a proposal aiming to enhance combat capacity of all police force in the next few years by standardizing information construction and increasing efficiency. Police performance management system is one of the important subject matter. In accordance with this proposal and for further optimizing the performance management system and solving the prob...学位：工程硕士院系专业：软件学院_工程硕士(软件工程)学号：X201323183

新型碳材料在钙钛矿太阳电池中的应用研究进展

A photoelectric conversion efficiency of 3.8% was achieved based on organic-inorganic hybrid perovskites CH_3NH_3PbBr_3 and CH_3NH_3PbI_3 in 2009, and their efficiencies have leaped to 20.1% in the past five years, which are comparable to Cu（In,Ga） Se_2

Semantic Memory Impairment and Lateralization in Brain Injured Patients

目的运用本土化的语义记忆测验评估脑损伤患者的语义记忆水平,比较患者和对照组在语义记忆分数上的差异,同时研究语义记忆是否存在偏侧化特点。方法对25例脑损伤患者（左侧脑损伤16例,右侧脑损伤9例）和24例正常对照组进行图片版和词汇版相关匹配测验。结果左侧脑损伤患者组在图片版和词汇版相关匹配测验上的分数均低于正常对照组（P〈0.01）和右侧脑损伤患者组（P〈0.05）。患者图片版和词汇版相关测验的分数之间呈明显正相关（r=0.542,P〈0.01）。左侧脑损伤语义记忆障碍发生率明显高于右侧脑损伤（P〈0.01）。左侧基底节损伤语义记忆障碍发生率高于右侧基底节损伤（P〈0.05）。结论采用词汇版和图片版相关匹配测验可评估患者语义记忆水平。脑损伤患者中普遍存在语义记忆障碍,而且语义记忆存在左侧化优势
